Phaser.Text crop not working on Phaser 2.6.2

[gcardozo]

I'm trying to crop a Phaser.Text, so I can make something similar to the As3 TextField class (where your text is inside of a mask). But the crop method is not working, here is what I did:

this.pText = new Phaser.Text(this.game, 0, 0, text, style);
this.pText.crop(new Phaser.Rectangle(0, 0, 20, 20), true);
this.pText.updateCrop();
